H07RN-F 3G2.5 identifies a harmonized flexible rubber cable in the 450/750 V class with three conductors, including a green-yellow protective-earth conductor, and a conductor area of 2.5 mm2 per core.
For a reliable result, read the complete marking as one matched reference entry. Looking at only part of the label—such as H07, RN-F, or 2.5—does not provide the full cable description.
H07RN-F 3G2.5 Segment Breakdown
| Segment | Current reference meaning |
|---|---|
| H07 | Harmonized cable, 450/750 V class |
| RN-F | Rubber insulation/jacket, flexible cord |
| 3G2.5 | Three cores including green-yellow earth, 2.5 mm2 |
Together, these segments describe the cable construction and conductor notation represented by the complete marking.
What H07RN-F Means
The H07RN-F portion identifies the cable as a harmonized cable in the 450/750 V class. Its RN-F designation indicates rubber insulation and jacket material in a flexible-cord description.
The full H07RN-F sequence should remain intact during verification. A cable marked only with H07 or only with RN-F is not the same complete marking and should not automatically be treated as an H07RN-F 3G2.5 match.
What 3G2.5 Means
The 3G2.5 portion describes the conductor arrangement:
3indicates three cores.Gindicates that the three cores include a green-yellow protective-earth conductor.2.5indicates a conductor area of 2.5 mm2.
Keep 3G2.5 together when checking a label or using a decoder. The conductor count, earth notation, and conductor area work together as part of the cable designation.
How to Verify the Marking
Use the complete visible label and compare it with the matched reference entry.
1. Confirm that the cable marking includes the full H07RN-F sequence.
2. Check that 3G2.5 appears as a complete conductor designation.
- Review the decoded segments: harmonized 450/750 V class, flexible rubber construction, three cores including protective earth, and 2.5 mm2 conductor area.
- Compare the full product label with the manufacturer data sheet before making a final decision.
The Cable Marking Decoder supports H07RN-F 3G2.5 as an exact reference entry. Its output is most useful as a label-reading aid that helps organize the visible information for comparison with original product documentation.
What the Marking Does Not Determine
An H07RN-F 3G2.5 cable marking does not, by itself, establish:
- Ampacity.
- Final installation permission.
- Procurement suitability.
- Local code compliance.
A conductor area or gauge shown in a marking does not independently determine ampacity. Manufacturer-specific suffixes and applicable local requirements may also change the final interpretation of a complete cable label.
Use the Decoded Result Correctly
Use the H07RN-F 3G2.5 Cable Marking result to identify the supported reference meaning: a harmonized 450/750 V-class flexible rubber cable with three 2.5 mm2 cores, including green-yellow protective earth.
Then verify the complete cable marking and manufacturer data sheet for the specific product under review. For related label-reading guidance, see How to Read Cable Markings, Cable Conductor Count and Earth Notation, and H05VV-F 3G1.5 Cable Marking.
